If you use an Android device, you’ll learn that not every app is available on the Google Play Store. Although it is highly recommended to download apps only from the Google Play Store, you may still want to sideload a particular app from a third-party site. This means you’ll have to download and install it manually.
When you attempt to do this, Google will give you several warnings and you may even have to change the settings on your device to be able to do this. That’s why it’s important to research the legitimacy of an app before sideloading it.
In order to further reduce the risk involved in downloading applications that have not been filtered by Google, it is recommended that you have a security app running in the background (like RedFox Mobile Security). Such an app will warn you in case apps try to perform all sorts of suspicious actions on your device.
